Welcome to the LDV NNR ringing blog, this blog is designed to share the experiences, findings and tales from a group of dedicated ringers. We specialise in conservation orientated research projects, largely focusing on wildfowl, waders, owls and birds of conservation concern, in and around the Vale of York NNR's.

NB - Whilst the purpose of this blog was initially designed to cover our nationally important wildfowl ringing activities, it now also features wildlife and work posts, explaining how we manage the NNR for both wildlife and people.

05/09/13 - It's all about the flora these days (& a bit of fauna)

After the very useful and enjoyable days spent with Judith in June and July finishing the vegetation quadrats for Long Term Monitoring Network, we went on to spend a morning together on Wheldrake Ings followed by an afternoon at Thornton Ellers searching for new plant species, adding many new grasses, sedges and rushes to the list.

With it being the end of August many butterflies were still out on Wheldrake as we made our way through the Purple Loosestrife towards the ditch-side where we started our search, passing along the way a number of species (figures are day totals) - Peacock (22), Small Tortoiseshell (202), Red Admiral (1), Small Copper (2), Comma (2), Small White (230), Green-veined White (20), Speckled Wood (7).

 Peaock (Inachis io) & Comma (Polygonum c-album)

 Red Admiral (Vanessa atalanta)

Here we came across: Water Stitchwort, Lesser Water Plantain, Celery-leaved Buttercup, Nodding Bur-marigold, Pink Water Speedwell, Water Pepper, Toad Rush, Common Winter-cress, and Many-seeded Goosefoot to name a few.

 Celery-leaved Buttercup (Ranunculus scleratus)

 Toad Rush (Juncus bufonius)

 Nodding Bur-marigold (Bidens cernua)

Pink Water Speedwell (Veronica catenata) 

Not only were the butterflies out in good numbers, but also many species of hoverfly, particularly the Helophilus genus, with H.trivittatus in abundance. We also came across a 'wasp mimic' which was new for the year - Sericomyia silentis.

Wasp mimic (Sericomyia silentis) 

From there we headed over to Thornton Ellers and in just a few hours we found 17 new grasses/sedges/rushes bringing our list to 56 for the year. Thornton Ellers is best described as an acidic fen surrounding alder woodland, here we came across species such as: Star Sedge, Bladder Sedge, Carnation Sedge, Pill Sedge, Velvet Bent, Brown Bent, Creeping Soft Grass and Purple Small-reed.

 Star Sedge (Carex echinata)

Aptly named - Hairy Sedge (Carex hirta) 

Even though it was late in the season many plant species could still be found such as - Enchanter's-nightshade, Harebell, Greater Bird's-foot Trefoil, Fen Bedstraw, Small Nettle, Common Stork's-bill, Climbing Corydalis and Field Pansy to name a few, however we also managed 7 new ones – some from the meadow and some from along the arable edges: Sun Spurge, Fiddleneck, Corn Spurrey, Heath Groundsel, Wall Speedwell, Parsley Piert and Marsh Cinquefoil.

Heath Groundsel (Senecio sylvaticus)

Fiddleneck (Amsinckia micrantha)

 Small Nettle (Urtica urens)

Judith with - Purple Small-reed (Calamagrostis canescens)

The weather was kind to us throughout the whole day with the sun bringing many butterflies to the Devil’s-bit Scabious which was out (one of the later flowering plants) and was humming with a variety of species: Small Copper (7), Small Tortoiseshell (29), Peacock (1), Red Admiral (1), Painted Lady (1), Brimstone (1), Common Blue (1), Wall Brown (1), Small White (11), Green-veined White (7), and 6 Speckled Wood on the nearby brambles.

Small Copper (Lycaena phlaeas)

 Green-veined White (Pieris napi)

Brimstone (Gonepteryx rhamni) 

Many invertebrates were also found including several new ones for the year: Oieceoptoma thoracicum (Red-breasted Carrion Beetle), Chorthippus albomarginatus (Lesser Marsh Grasshopper), Piezodorus lituratus (Gorse Shield Bug), Psyllobora 22-punctata (22-spot Ladybird), Evacanthus interruptus (Yellow & black Leaf Hopper), Philaenus spumarius (Common Leaf Hopper), Poecilus versicolor (Ground Beetle) and Platycheirus granditarsus (Hoverfly).

 Lesser Marsh Grasshopper (Chorthippus albomarginatus)

Common Green Grasshopper (Omocestus viridulus)

22-spot Ladybird (Psyllobora 22-punctata)

Common Flesh Fly (Sarcophaga carnaria) 

Gorse Shield Bug (Piezodorus lituratus)


  1. Nice to see some flies on the blog!

    The Helophilus shown is pendulus (black face stripe and hind tibiae mainly yellow) and the Sarcophaga is almost certainly not carnaria (far more uncommon than general insect books suggest!), but can't be taken to species without a gen. det. Sericomyia silentis is a nice one, which is found commonly on Heather at Allerthorpe.

  2. Thanks Ian, and for the corrections, I'm afraid it's just help from Collins etc for novices like ourselves re the Carnaria, however the Helophilus is a case of right name wrong photo!

  5. The internet used to be a safe haven to gather new knowledge in the comfort of your space until these scammers sprouted out of the blue like worms and made it unsafe. I am a country music lover, and Kenny Rogers is my idol. I can remember when a notification from Instagram popped on my screen, Guess who, my idol. I was awed and I can remember myself writing about all his impact in my life. I was so sure I was talking to my idol on Instagram. He did say he wanted to introduce me to this quick money-making scheme because he noticed I have been a loyal fan on his official IG page. My idol can never go wrong in my eyes and didn't even do any research. I hurriedly joined the scheme. I never knew it was a scammer posing as a celebrity till I had invested $540.000.00. It got worse when I couldn't access my account or withdraw from my investment, I knew there was a problem after all these happenings. I need to get help from any means to ensure I am not a victim of these parasites. I was glad to be able to be introduced to the best CRYPTOCURRENCY RECOVER EXPERT known as Spyhost Cyber Security Company.
